Question

linear equation solve. Please help
1/2x+6/5=2/5x
My answer was a -12 but it wont check

Answer 1

6/5 = 2/5x - 1/2x
6/5 = -1/10x
-12 = x

So you are correct!

1/2(-12)+6/5 = 2/5 (-12)
-6 +6/5 = -24/5
-30+6/5=-24/5
-24/5 = -24/5

So it does check!

Answer 2

Answer 3

when i am multiplying do i have to have a LCD or the same denominator?

Answer 4

No. When you are multiplying fractions, the denominator does not have to be the same. However, the denominators must be the same for addition.

Answer 5

how about
17/16x+x/16=6x+1/8+15/16x
I got x=-2/93
